The present invention relates to the field of lettuce breeding, in particular to Quantitative Trait Loci for resistance against the lettuce aphid Nasonovia ribisnigri biotype Nr:1 and to cultivated lettuce comprising one or more of these Quantitative Trait Loci.

The present invention relates to a Lactuca sativa seed designated 79-856 RZ. The present invention also relates to a Lactuca sativa plant produced by growing the 79-856 RZ seed. The invention further relates to methods for producing the lettuce cultivar, represented by lettuce variety 79-856 RZ.

Novel lettuce, such as lettuce designated FLOWCUT is disclosed. In some embodiments, the disclosure relates to the seeds of lettuce designated FLOWCUT, to the plants and plant parts of lettuce designated FLOWCUT, and to methods for producing a lettuce plant by crossing the lettuce designated FLOWCUT with itself or another lettuce plant. The disclosure further relates to methods for producing a lettuce plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other lettuce plants derived from the lettuce designated FLOWCUT.

The invention provides seed and plants of the lettuce line SV2988LG. The invention thus relates to the plants, seeds, and tissue cultures of lettuce line SV2988LG, and to methods for producing a lettuce plant produced by crossing a plant of lettuce line SV2988LG with itself or with another lettuce plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of a plant of lettuce line SV2988LG, including the gametes of such plants.

New lettuce variety designated ‘Marciano’ is described. ‘Marciano’ is a lettuce variety exhibiting stability and uniformity.

The invention provides seed and plants of the lettuce line SVLD1594. The invention thus relates to the plants, seeds, and tissue cultures of lettuce line SVLD1594, and to methods for producing a lettuce plant produced by crossing a plant of lettuce line SVLD1594 with itself or with another lettuce plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of a plant of lettuce line SVLD1594, including the gametes of such plants.

Novel lettuce, such as lettuce designated PINION is disclosed. In some embodiments, the disclosure relates to the seeds of lettuce designated PINION, to the plants and plant parts of lettuce designated PINION, and to methods for producing a lettuce plant by crossing the lettuce designated PINION with itself or another lettuce plant. The disclosure further relates to methods for producing a lettuce plant containing in its genetic material one or more transgenes and to the transgenic plants produced by that method and to methods for producing other lettuce plants derived from the lettuce designated PINION.

The present invention is directed toward lettuce plants, designated Long Stem lettuce, having a long stern that elevates the lettuce head high up off the ground compared to commercial lettuce varieties, which lends it to be harvested easily by any process, whether manually or mechanically. The invention relates to the seeds, plants, and plant parts of Long Stem lettuce plants and to methods for producing a lettuce plant by crossing Long Stem lettuce with itself or another lettuce cultivar. The invention further relates to methods for producing a lettuce plant containing in its genetic material one or more transgenes and to the transgenic lettuce plants and plant parts produced by those methods. This invention also relates to lettuce cultivars or breeding cultivars and plant parts derived from Long Stem lettuce, to methods for producing other lettuce cultivars, lines or plant parts derived from Long Stem lettuce and to the lettuce plants, varieties, and their parts derived from the use of those methods.

New lettuce variety designated ‘Dark Horse’ is described. ‘Dark Horse’ exhibits stability and uniformity.

New lettuce varieties designated ‘E01G11546’, ‘E01G11538’, ‘E01G11244’, and ‘E01G11679’ are described. ‘E01G11546’, ‘E01G11538’, ‘E01G11244’, and ‘E01G11679’ are lettuce varieties exhibiting stability and uniformity.
